Termination of Multiple Direct Vent Furnaces
The vent/flue and combustion air pipes may terminate vertically,
as through a roof, or horizontally, as through an outside wall.
Vent/Intake Terminations For Installation of
Multiple Direct Vent Furnaces
If more than one direct vent furnace is to be installed vertically
through a common roof top, maintain the same minimum
clearances between the exhaust vent and air intake terminations of
adjacent units as with the exhaust vent and air intake terminations
of a single unit.
If more than one direct vent furnace is to be installed horizontally
through a common side wall, maintain the clearances as in the
following figure. Always terminate all exhaust vent outlets at the
same elevation and always terminate all air intakes at the same
elevation.
Concentric Vent Termination
Refer to the directions provided with the Concentric Vent Kit
(DCVK) for installation specifications.
Side Wall Vent Kit
This kit is to be used with 2" or 3" direct vent systems. The vent
kit must terminate outside the structure and may be installed
with the intake and exhaust pipes located side-by-side or with
one pipe above the other. These kits are NOT intended for
use with single pipe (indirect vent) installations.
Refer to the directions furnished with the Side Wall Vent
Kit (p/n 0170K00000S or 0170K00001S) for installation
specifications.

Condensate Drain Lines & Drain Trap
A condensing gas furnace achieves its high level of efficiency by
extracting heat from the products of combustion to the point where
condensation takes place. The condensate must be collected
in the furnace drain trap and routed to an appropriate drain
location in compliance with local and national codes.
